You are making an incorrect assumption about how many of us come to our conclusions.
That scientists know the truth but aren't telling the population? If you have to resort to conspiracy, your on flimsy ground. Again, with priors like that you can believe anything you want. That's why conspiracy theories are so rampant in the first place.
If you really believe that then why are you listening to anything Ray has to say, as most of what he recommends is refuted by the majority of the experts, including his denial of man made global warming.
I think we've been over this, but I'll lay out my position again:
1) Human biochemistry is a lot more complex and studies are limited and much more prone to error than studying less complex systems like climate or physics.
2) I don't take Ray's word for gospel. I experiment with some of his ideas and take what I find useful and discard the rest.
I think it's strange that you want to throw out all of modern science (or at least the stuff you disagree with) on the basis of Ray might get some things right about nutrition that the mainstream gets wrong. That's a bad idea and ties into my initial criticism of you that your line of thinking that you want to cry ad hominen about.
